Description:

Trimethylchlorosilane is a colorless and transparent liquid with a pungent odor. When exposed to the air, it easily reacts with moisture to generate hydrogen chloride. Relative density 0.846, melting point -40℃, boiling point 57℃, refractive index 1.3884, flash point -28℃, flammable, toxic and corrosive.

 

Production method :

Methyl chloride and silicon powder are directly synthesized in the next step catalyzed by cuprous chloride to generate methylchlorosilane mixture, which can be purified by rectification to obtain trimethylchlorosilane and other monomers.
